This add-on will show the todays users in the sidebar under the online user list.
ATTENTION, it's NOT SHOWING the visitors from the last 24h, instead it's showing only TODAYS visitors.
So if somebody is visiting at 00:01 he'll probably see only him^^
only users with valid user_state (so nobody with "waiting mail confirm" status will be shown AND banned users will be also ignored)
